First Embodiment

FIG. 1 is a perspective view for illustrating an entire configuration ofa liquid crystal display device 1 according to this embodiment. Asillustrated in FIG. 1, the liquid crystal display device 1 according tothis embodiment includes a display panel 10, an upper frame 20, and alower frame 30. The display panel 10 includes a TFT substrate 11, a CFsubstrate 12, a liquid crystal layer (not shown) sandwiched between boththe substrates, and a backlight unit (not shown) configured to radiatelight from the back surface side. Further, the display panel 10 assupported between the upper frame 20 arranged on the front surface sideof the display panel 10 (front surface side of the CF substrate 12) andthe lower frame 30 arranged on the back surface side of the displaypanel 10 (back surface side of the TFT substrate 11).

The display region 101 Includes a plurality of data lines 13 extendingin a column direction, and a plurality of gate lines 14 extending in arow direction. The respective data lines 13 are electrically connectedto a source driver 230. The respective gate lines 14 are electricallyconnected to a gate driver 240. A plurality of pixels 15 are arranged inmatrix (row direction and column direction) so as to correspond torespective intersecting portions of the respective data lines 13 and therespective gate lines 14. For each pixel 15, a thin film transistor 16,a pixel electrode 17, and a common electrode 18 are formed. The thinfilm transistor 16 is formed at each intersecting portion between eachdata line 13 and each gate line 14.

The non-display region 102 includes a driving circuit (source driver 230and gate driver 240) configured to cause image display in the displayregion 101. The driving circuit is arranged at a peripheral portion ofthe display region 101 in plan view. Specifically, in plan view, thegate driver 240 is arranged on the left side of the display region 101,and the source driver 230 is arranged on the upper side of the displayregion 101. Note that, the arrangement of the driving circuit is notlimited to the example illustrated in FIG. 2. For example, in plan view,the gate driver 240 may be arranged on each of the left side and theright side of the display region 101, or the gate driver 240 may bearranged on any one of the left side and the right side of the displayregion 101. Further, in plan view, the source driver 230 may be arrangedon each of the upper side and the lower side of the display region 101,or the source driver 230 may be arranged on any one of the upper sideand the lower side of the display region 101.

FIG. 3 is a sectional view for illustrating an example of theconfiguration of the liquid crystal display device 1 according to afirst embodiment of the present invention. The liquid crystal displaydevice 1 includes the display panel 10, the upper frame 20, and thelower frame 30. The display panel 10 includes the TFT substrate 11arranged on the back surface side, the CF substrate 12 arranged on thefront surface side, a liquid crystal layer 130 sandwiched between theTFT substrate 11 and the CF substrate 12, a sealing member 140surrounding the liquid crystal layer 130 and being sandwiched betweenthe TFT substrate 11 and the CF substrate 12, and a backlight unit 150configured to radiate light from the back surface side.

In the TFT substrate 11, the gate lines 14 are formed on a glasssubstrate 111, and an insulating film 112 is formed so as to cover thegate lines 14. Further, the data lines 13 are formed on the insulatingfilm 112, and an insulating film 113 is formed so as to cover the datalines 13. Further, the common electrode 13 is formed on the insulatingfilm 113, and an insulating film 114 is formed so as to cover the commonelectrode 18. Further, the pixel electrode 27 is formed on theinsulating film 114, and an alignment film (not shown) is formed so asto cover the pixel electrode 17. Although not shown, a polarizing plateand the like are further formed in the TFT substrate 11.

In the CF substrate 12, a non-light transmitting layer 122 (blackmatrix) configured to restrict the transmission of light and a coloredlayer 123 (for example, a red color filter 123 r, a green color filter123 g, and a blue color filter 123 b) configured to transmit light areformed on a glass substrate 121, and an overcoat layer 124 is formed soas to cover those layers. Further, an alignment film (not shown) isformed on the overcoat layer 124. Although not shown, a polarizing plateand the like are further formed in the CF substrate 12. Further, in theCF substrate 12, the non-light transmitting layer 122 and the coloredlayer 123 are formed an a stripe pattern in the display region 101, andthe non-light transmitting layer 122 is formed in the non-display region102.

The TFT substrate 11 is formed into a rectangular shape that is largerthan the CF substrate 12, and terminals to be electrically connected tovarious wirings such as the data lines 13 and the gate lines 14 arearranged at a peripheral, edge portion that does not overlap with the CFsubstrate 12. In FIG. 3, a gate terminal 241 electrically connected tothe gate line 14 is arranged, and the gate driver 240 is mounted on thegate terminal 241. Note that, the gate terminal 241 may be electricallyconnected to a flexible printed board having the gate driver 240 mountedthereon.

A method of driving the liquid crystal display device 1 is simplydescribed. A data signal (data voltage) is supplied to each of the datalines 13 from the source driver 230. A gate signal (gate voltage) issupplied to each of the gate lines 14 from the gate driver 240. A commonvoltage Vcom is supplied to the common electrode 18 via a common wiring(not shown). When an ON voltage of a gate signal (gate ON voltage) issupplied to a gate line 14, a thin film transistor 16 connected to thegate line 14 is turned on, rand the data voltage is supplied to a pixelelectrode 17 via a data line 13 connected to the thin film transistor16. An electric field is generated due to a difference between the datavoltage supplied to the pixel electrode 17 and the common voltage Vcomsupplied to the common electrode 19. The electric field drives theliquid crystal to control transmittance of light emitted from thebacklight unit 150, thereby displaying an image. Note that, when colordisplay is performed, the display is realized by supplying a desireddata voltage to each of the data lines 13 connected to pixel electrodes17 of pixels 15 corresponding to a red color filter 123 r, a green colorfilter 123 g, and a blue color filter 123 b formed with stripe-likecolor filters. Note that, the common electrode 18 may be formed on theTFT substrate 11, or may be formed on the CF substrate 12. Theabove-mentioned method of driving the liquid crystal, display device 1is merely an example, and other known methods can also be employed.

In this case, when a pulsed gate signal is applied to the gate line 14from the gate driver 240 to display an image on the liquid crystaldisplay device 1, electric charges 300 generated by wiring coupling inthe gate line 14 propagate to the display region 101 through thenon-light transmitting layer 122, and an electric field is generatedbetween the electric charges 300 and the pixel electrode 17. Asdescribed above, in the liquid crystal display device 1, an image isdisplayed by controlling the transmittance of light passing through theliquid crystal layer 130 based on the electric field formed between thepixel electrode 17 and the common electrode 18. When the electric fieldformed between the electric charges 300 and the pixel electrode 17 isapplied to the liquid crystal layer 130, the molecule alignment of theliquid crystal is changed, with the result that an unintended colordisplay (color change) may occur in the display image.

In the first embodiment, a first slit 125 is formed in the non-lighttransmitting layer 122 formed in the non-display region 102 of the CFsubstrate 12. Thus, the influence on a display image due to propagationto the display region 101 of the electric charges 300 generated bywiring coupling of the gate line 14 is reduced.

Now, the configuration of the first slit 125 formed in the non-lighttransmitting layer 122 according to the first embodiment is specificallydescribed.

FIG. 4 is a view for illustrating a first example of the first slit 125formed in the non-light transmitting layer 122 according to the firstembodiment. FIG. 4 is a plan view of the display panel 10 as viewed fromthe CF substrate 12 side. As illustrated in FIG. 4, in the non-displayregion 102 formed into a frame shape surrounding the display region 101,the source driver 230, the gate driver 240, the non-light transmittinglayer 122, and the first slit 125 are formed. In FIG. 4, theillustration of the inside of the display region 101 and theIllustration of various wirings such as the data lines 13 and the gatelines 14 are emitted.

The display region 101 is a substantially rectangular region having foursides, specifically, a first side 161 to a fourth side 164. The displayregion 101 includes two sides (first side 161 and fourth side 164)extending in the column direction, and two aides (second side 162 andthird side 163) connecting together the first side 161 and the fourthside 164 and extending in the row direction. Further, the gate driver240 is arranged on one or both of the first side 165 side and the fourthside 164 side. Further, the source driver 230 is arranged on one or bothof the second side 162 side and the third side 163 side.

The non-display region 102 is a frame-shaped region having four regions,specifically, a first region 102A to a fourth region 102D. In thenon-display region 102, the first region 102A refers to a region inwhich the gate driver 240 is arranged, and the second region 102B refersto a region in which the source driver 230 is arranged. The secondregion 102B refers to one of two regions in contact with the firstregion 102A, and the third region 102C refers to the other of the tworegions in contact with the first region 102A (region opposed to thesecond region across the display region). The fourth region 102D refersto a region in contact with the second region 102B and the third region102C and opposed to the first region 102A (region opposed to the firstregion across the display region). Note that, in FIG. 4, there isillustrated an example in which the gate driver 240 is arranged on thefirst side 161 side of the display region 101, but the gate driver 240may be arranged on the fourth side 164 side of the display region 101.In this case, the first region 102A corresponds to the region on thefourth side 164 side, in which the gate driver 240 is arranged. Notethat, the gate driver 240 may be arranged in both of the first region101A and the fourth region 104D. Further, in FIG. 4, there isillustrated an example in which the source driver 230 is arranged on thesecond side 162 side of the display region 101, but the source driver230 may foe arranged on the third side 163 side or the display region101. In this case, the second region 102B corresponds to the region onthe third side 163 side, in which the source driver 230 is arranged.Note that, the source driver 230 may be arranged in both of the secondregion 102B and the third region 102C.

In the non-light transmitting layer 122 formed in the non-display region102 illustrated in FIG. 4, the first slit 125 is formed, which extendsthrough the first region 102A in which the gate driver 210 is arrangedand the second region 102B. The first slit 125 is formed so as to passthrough the non-light transmitting layer 122. The first slit 125illustrated in FIG. 4 is a single continuous slit, which seamlesslyextends through the first region 102A and the second region 102B. Inother words, one of the two end portions (first end portion E1) of thefirst slit 125 is included in the first region 102A, and the otherthereof (second end portion E2) is included in the second region 102B.Further, the first slit 125 illustrated in FIG. 4 extends linearly alongthe first side 161 of the display region 101 in the first region 102A,and extends linearly along the second side 162 of the display region 101in the second region 102B. Therefore, the first slit 125 is formed so asto be bent substantially at a right angle at a corner portion of thenon-display region 102 (corner portion at which the first region 102Aand the second region 1028 are in contact). Note that, the first slit125 is not limited to an example of being formed so as to be bentsubstantially at a right angle at the corner portion of the non-displayregion 102. For example, the first slit 125 may be formed so as to becurved into an arc shape at the corner portion of the non-display region102. Further, the first slit 125 may be formed into a shape extendingalong the outer shape of the display region 301.

Note that, in FIG. 4, the first slit 125 extends through two regions,specifically, the first region 102A and the second region 102B, but thefirst slit 125 is not limited to this example. For example, the firstslit 125 may extend through the first region 102A and the third region102C.

The first slit 325 is formed so as to extend through the first region102A in which the gate driver 240 is arranged and through the secondregion 102B formed in contact with the first region 102A. Thus, theelectric charges 300 generated by the wiring coupling of the gate line14 in the first, region 102A move on the outer side of the first slit125 to reach the first end portion E1 included in the first region 102Aor the second end portion E2 included in the second region 102B, tothereby propagate to the display region 101. As described above, withthis configuration, as compared to the case where the slit is formedonly in the region in which the gate driver 240 is arranged, a path forthe electric charges 300 generated by the wiring coupling of the gateline 14 to propagate to the display region 101 can be taken longer. Withthis, the influence on the display image due to the electric chargesgenerated by the wiring coupling of the gate line 14 is reduced.

FIG. 5 is a view for illustrating a second example of the first slit 125formed in the non-light transmitting layer 122 according to the firstembodiment. FIG. 5 is a plan view of the display panel 10 as viewed fromthe CF substrate 12 side. The second example of the first slit 125illustrated in FIG. 6 differs from the first example of the first slit125 illustrated in FIG. 4 in the shape of the first slit 125, but otherpoints are the same. Therefore, configurations similar to those in thefirst example of the first slit 125 illustrated in FIG. 4 are denoted bythe same reference symbols, and redundant description thereof is omittedherein.

In the non-light transmitting layer 122 formed in the non-display region102 illustrated in FIG. 5, the first slit 125 is formed, which extendsthrough the first region 102A in which the gate driver 240 is arranged,the second region 102B, and the fourth region 102D. The first slit 125is formed so as to pass through the non-light transmitting layer 122.The first slit 125 illustrated in FIG. 5 is a single continuous slit,which seamlessly extends through the first region 102A, the secondregion 102B, and the fourth region 102D. In other words, one of the twoend portions (first end portion E1) of the first slit 12 b is includedin the first region 102A, and the other thereof (second end portion E2)is included in the fourth region 102D. The first slit 125 illustrated inFIG. 5 extends linearly along the first side 161 of the display region101 in the first region 102A, extends linearly along the second side 162of the display region 101 in the second region 102B, and extendslinearly along the fourth side 164 of the display region 101 in thefourth region 102D. Therefore, the first slit 125 is formed so as to bebent substantially at a right angle at a corner portion of thenon-display region 102 (corner portion at which the first region 102Aand the second region 102B are in contact and corner portion at whichthe second region 102B and the fourth region 102D are in contact). Notethat, the first slit 125 is not limited to an example of being formed soas to be bent substantially at a right angle at each corner portion. Forexample, the first slit 125 may be formed so as to be curved into an arcshape at each corner portion. Further, the first slit 125 may be formedinto a shape extending along the outer shape of the display region 101.

The first slit 126 is formed so as to extend through the first region102A in which the gate driver 240 is arranged, the second region 102B,and the fourth region 102D. Thus, the electric charges 300 generated bythe wiring coupling of the gate line 14 move on the outer side of thefirst slit 125 to reach the first end portion E1 included in the firstregion 102A or the second end portion E2 included in the fourth region102D, to thereby propagate to the display region 301. With thisconfiguration, as compared to the case where the slit is formed only inthe region in which the gate driver 240 is arranged, a path for theelectric charges 300 generated by the wiring coupling of the gate line14 to propagate to the display region 101 can be taken longer. Withthis, the influence on the display image due to the electric chargesgenerated by the wiring coupling of the gate line 14 is reduced.

Note that, in FIG. 5, the first slit 125 extends through three regions,specifically, the first region 102A, the second region 102B, and thefourth region 102D, but the first slit 125 is not limited to thisexample. For example, the first slit 125 may extend through the firstregion 102A, the third region 102C, and the fourth region 102D.

FIG. 6 is a view for illustrating a third example of the first slit 125formed in the non-light transmitting layer 122 according to the firstembodiment. FIG. 6 is a plan view of the display panel 10 as viewed fromthe CF substrate 12 side. The third example of the first slit 125illustrated in FIG. 6 differs from the first example of the first slit125 illustrated in FIG. 4 in the shape of the first slit 125, but otherpoints are the same. Therefore, configurations similar to those in thefirst example of the first slit 126 illustrated in FIG. 4 are denoted bythe same reference symbols, and redundant description thereof is omittedherein.

In the non-light transmitting layer 122 formed in the non-display region102 illustrated in FIG. 6, the first slit 125 is formed, which extendsthrough the first region 102A in which the gate driver 240 is arrangedand the second region 102B, and further through the first region 102A inwhich the gate driver 240 is arranged and the third region 102C. Thefirst slit 125 is formed so as to pass through the non-lighttransmitting layer 122. The first slit 125 illustrated in FIG. 6 is asingle continuous slit, which seamlessly extends through the firstregion 102A, the second region 102 b, and the third region 102C. Inother words, one of the two end portions (first end portion E1) of thefirst slit 125 is included in the second region 102B, and the otherthereof (second end portion E2) is included in the third region 102C.Further, the first slit 125 illustrated in FIG. 6 extends linearly alongthe first side 161 of the display region 101 in the first region 102A,extends linearly along the second side 162 of the display region 101 inthe second region 102B, and extends linearly along the third side 163 ofthe display region 101 in the third region 102C. Therefore, the firstslit 125 is formed so as to be bent substantially at a right angle at acorner portion of the non-display region 102 (corner portion at whichthe first region 102A and the second region 102B are in contact andcorner portion at which the first region 102A and the third region 102Care in contact). Note that, the first slit 125 is not limited to anexample of being formed so as to be bent substantially at a right angleat each corner portion. For example, the first slit 125 may be formed soas to be curved into an arc shape at each corner portion. Further, thefirst slit 125 may be formed into a shape extending along the outershape of the display region 101.

The first slit 125 is formed so as to extend through the first region102A in which the gate driver 240 is arranged, the second region 102B,and the third region 102C. Thus, the electric charges 300 generated bythe wiring coupling of the gate line 14 move on the outer side of thefirst slit 125 to reach the first end portion E1 included in the secondregion 102B or the second end portion E2 included in the third region102C, to thereby propagate to the display region 101. With thisconfiguration, no matter which direction the electric charges 300generated by the wiring coupling of the gate line 14 propagate betweentoward the first end portion E1 and toward the second end portion E2 ofthe first slit 125, a distance for the electric charges 300 to propagateto the display region 101 can be taken long. With this, the influence onthe display image duo to the electric charges 300 generated by thewiring coupling of the gate line 14 is reduced.

FIG. 7 is a view for illustrating a fourth example of the first slit 126formed in the non-light transmitting layer 122 according to the firstembodiment. FIG. 7 is a plan view of the display panel 10 as viewed fromthe CF substrate 12 side. The fourth example of the first slit 125illustrated in FIG. 7 differs from the first example of the first slit125 illustrated in FIG. 4 in the shape of the first slit 125, but otherpoints are the same. Therefore, configurations similar to those in thefirst example of the first slit 125 illustrated in FIG. 4 are denoted bythe same reference symbols, and redundant description thereof is omittedherein.

In the non-light transmitting layer 122 formed in the non-display region102 illustrated in FIG. 7, the first slit 125 is formed, which extendsthrough the first region 102A in which the gate driver 240 is arranged,the second region 102B, and the fourth region 102D, and further throughthe first region 102A, the third region 102C, and the fourth region102D. The first slit 125 is formed so as to pass through the non-lighttransmitting layer 122. The first slit 125 illustrated in FIG. 7 is asingle continuous slit, which seamlessly extends through the firstregion 102A, the second region 102B, the third region 102C, and thefourth region 102D. In other words, the two end portions (first endportion E1 and second end portion E2) of the first slit 125 are includedin the fourth region 102D. In this case, the first end portion E1 andthe second end portion E2 are formed for the purpose of releasing thestatic electricity generated in the display region 101 to the outside ofthe display region 101, and the first slit 125 does not surround theentire circumference of the display region 101 in the present invention.Further, the first slit 125 illustrated in FIG. 7 extends linearly alongthe first side 161 of the display region 101 in the first region 102A,extends linearly along the second side 162 of the display region 101 inthe second region 102B, extends linearly along the third side 163 of thedisplay region 101 in the third region 102C, and extends linearly alongthe fourth side 164 of the display region 101 in the fourth region 102D.Therefore, the first slit 125 is formed so as to be bent substantiallyat a right angle at a corner portion oi the non-display region 102(corner portion at which the first region 102A and the second region102B are in contact, corner portion at which the first region 102A andthe third region 102C are in contact, corner portion at which the secondregion 102B and the fourth region 102D are in contact, and cornerportion at which the third region 102C and the fourth region 102D are incontact). Note that, the first slit 125 is not limited to an example ofbeing formed so as to be bent substantially at a right angle at eachcorner portion. For example, the first slit 125 may be formed so as tobe curved into an arc shape at each corner portion. Further, the firstslit 125 may be formed into a shape extending along the outer shape ofthe display region 101.

The first slit 125 is formed so as to extend through the first region102A in which the gate driver 240 is arranged, the second region 102B,the third region 102C, and the fourth region 102D. Thus, the electriccharges 300 generated by the wiring coupling of the gate line 14 move onthe outer side of the first slit 125 to reach the first end portion E1or the second end portion E2 included in the fourth region 102D, tothereby propagate to the display region 101. With this configuration, nomatter which direction the electric charges 300 generated by the wiringcoupling of the gate line 14 propagate between toward the first endportion E1 and toward the second end portion E2 of the first slit 125, adistance for the electric charges 300 to propagate to the display region101 can be taken long. With this, the influence on the display image dueto the electric charges 300 generated by the wiring coupling of the gateline 14 is reduced.

Note that, in FIG. 7, the first slit 125 extends through four regions,specifically, the first region 102A, the second region 102B, the thirdregion 102C, and the fourth region 102D, and the two end portions of thefirst slit 125 are arranged in the fourth region 102D. However, thefirst slit 125 is not limited to this example. For example, the two endportions of the first slit 125 may be arranged in the second region102B, or may be arranged in the third region 102C.

Further, in the third example of the first slit 125 illustrated in FIG.6 and the fourth example of the first slit 125 illustrated in FIG. 7,the first slit 125 may be arranged so as to be line symmetric withrespect to the center line in the column direction of the display region101. When the first slit 125 is arranged to be line symmetric withrespect to the center line in the column direction of the display region101, the distance that the electric charges 300 generated by the wiringcoupling of the gate line 14 move can be equalized between the casewhere the electric charges 300 propagate to the display region 101 fromthe first end portion E1 and the case where the electric charges 300propagate to the display region 101 from the second end portion E2.

In the examples of the first slit 12 b according to the first embodimentdescribed above, there is described an example in which the single firstslit 125 is formed, but a plurality of first slits 125 may be formed.

FIG. 8 is a view for illustrating a fifth example of the first slit 125formed in the non-light transmitting layer 122 according to the firstembodiment. In FIG. 8, the gate drivers 240 (gate driver 240 a and gatedriver 240 b) are arranged in both of the first region 102A and thefourth region 102D. In this case, each of the two gate drivers 240applies a pulsed gate signal to the gate line 14, and hence the electriccharges 300 are generated by the wiring coupling of the gate line 14 ineach of the first region 102A and the fourth region 102D. In view ofthis, as illustrated in FIG. 8, two first slits 125 (first slit 125 aand first slit 125 b) are formed so as to correspond to the regions(first region 102A and fourth region 102D) in which the two gate drivers240 are arranged. For example, in the non-light transmitting layer 122formed in the non-display region 102 illustrated in FIG. 8, the firstslit 125 a is formed, which extends through the first region 102A inwhich the gate driver 240 a is arranged and the second region 102B, andfurther through the first region 102A and the third region 102C. Thefirst silt 125 a is a single continuous slit, which seamlessly extendsthrough the first region 102A, the second region 102B, and the thirdregion 102C. One of the two end portions (first end portion E1 a) of thefirst slit 125 a is included in the second region 102B, and the otherthereof (second end portion E2 a) is included in the third region 102C.

Further, in the non-light transmitting layer 122 formed in thenon-display region 102, the first slit 125 b is formed, which extendsthrough the fourth region 102D in which the gate driver 240 b isarranged and the second region 102B, and further through the fourthregion 102D and the third region 102C. The first slit 125 b is a singlecontinuous slit, which seamlessly extends through the second region102B, the third region 102C, and the fourth region 102D. One of the twoend portions (first end portion E1 b) of the first slit 125 b isincluded in the second region 102B, and the other thereof (second endportion E2 b) is included in the third region 102C.

Further, the length of the first slit 125 a may be equal to the lengthof the first slit 125 b. For example, as illustrated in FIG. 8, thefirst slit 3.25 a and the first slit 125 b may be arranged so as to beline symmetric with respect to the center line in the row direction ofthe display region 101. When the length of the first slit 125 a is setequal to the length of the first slit 125 b as described above, thedistance for the electric charges 300 generated in the first region 102Ato propagate to the display region 101 can be set equal to the distancefor the electric charges 300 generated in the fourth region 102D topropagate to the display region 101.

Note that, the first slit 125 a may be formed so as to extend throughthe first region 102A and the second region 102B, and the first slit 125b may be formed so as to extend through the third region 102C and thefourth region 102D. Further, the first slit 125 a may be formed so as toextend through the first region 102A and the third region 102C, and thefirst slit 125 b may be formed so as to extend through the second region102B and the fourth region 102D.

Further, the first slit 125 maybe formed so as to extend through theregion in which the gate driver 240 is arranged and the region in whichthe source driver 230 is arranged. Specifically, for example, when thegate driver 240 is arranged in the first region 102A and the sourcedriver 230 is arranged in the third region 102C, the first slit 125 maybe formed so as to extend through the first region 102A and the thirdregion 102C. Further, when the gate driver 240 is arranged in each ofthe first region 102A and the fourth region 102D and the source driver230 is arranged in the second region 102B, as illustrated in FIG. 5, thefirst slit 125 may be formed so as to extend through the first region102A, the second region 102B, and the fourth region 102D. In the liquidcrystal display device 1, there is a case where the source driver 230supplies a control signal to the gate driver 240. In this case, acontrol signal line configured to supply a control signal from thesource driver 230 to the gate driver 240 is arranged at the cornerportion of the non-display region 102, and hence there is a fear in thatthe electric charges 300 generated by the wiring coupling of the controlsignal line arranged at the corner portion may propagate to the displayregion 101. In such a case, when the first slit 125 is formed so as toextend through the region in which the gate driver 240 is arranged andthe region in which the source driver 230 is arranged, the influence onthe display image due to the electric charges 300 generated by thewiring coupling of the control signal line arranged at the cornerportion of the non-display region 102 can be reduced.

Second Embodiment

In a second embodiment of the present invention, in addition to thefirst slit 125 described in the first embodiment, a second slit 126different from the first slit 125 is formed. FIG. 9 is a sectional viewfor illustrating an example of the configuration of the liquid crystaldisplay device 1 according to the second embodiment. The sectionalstructure of the liquid crystal display device 1 according to the secondembodiment illustrated in FIG. 9 differs from the sectional structure ofthe liquid crystal display device 1 according to the first embodimentillustrated in FIG. 3 in the point that the second slit 126 is included,but other points are the same. FIG. 10 is a view for illustrating afirst example of the second slit 126 formed in the non-lighttransmitting layer 122 according to the second embodiment. FIG. 10 is aplan view of the display panel 10 as viewed from the CF substrate 12side. The second embodiment illustrated in FIG. 10 differs from thefirst embodiment illustrated in FIG. 4 in the point that the second slit126 is included, but other points are the same. Therefore, in FIG. 9 andFIG. 10, configurations similar to those in the first embodiment aredenoted by the same reference symbols, and redundant description thereofis emitted herein.

In the non-light transmitting layer 122 formed in the non-display region102 illustrated in FIG. 10, first, the first slit 125 is formed. Forexample, as illustrated in FIG. 10, the first slit 125 is formed so asto extend through the first region 102A in which the gate driver 240 isarranged and the second region 102B. Note that, the first slit 125 maybe formed into the shape illustrated in FIG. 5 to FIG. 8. Then, in thenon-light transmitting layer 122 formed in the non-display region 102,the second slit 126 different from the first slit 125 is formed inaddition to tire first slit 125. The second slit 126 illustrated In FIG.10 is a single continuous slit, which is formed through the first region102A, the second region 102B, the third region 102C, and the fourthregion 102D.

The second slit 126 is formed so as to extend on the inner side (displayregion 101 side) of each of the two end portions of the first slit 125.When the second slit 126 is not formed, the electric charges 300generated by the wiring coupling of the gate line 34 move to the displayregion 101 from the first end portion E1, for example. In order to avoidsuch movement of the electric charges 300 to the display region 101 fromthe end portion of the first slit 125, the second slit 126 may be formedso as to extend at least on the inner side (display region 101 side) ofeach of the two end portions of the first slit 125. In other words, in adirection in which the end portion of the first slit 125 reaches thedisplay region 101 at a shortest distance (in this case, the columndirection), the end portion of the first slit 125 is prevented fromoverlapping with the end portion of the second slit 126. In other words,the second slit 126 is formed so that, when the non-display region 102is viewed from the display region 101, the second slit 126 covers theend port ion of the first slit 125. Further, a part of the second silt326 is formed along the first slit 125 and between the first slit 125and the display region 101. With this, the path tor the electric charges300 generated by the wiring coupling of the gate line 14 to propagate tothe display region 103 can be taken long.

Further, it is preferred that a part of the second slit 126 be formed ina region in which the first slit 125 is not formed in the non-displayregion 102. With this, in the non-display region 102, the first slit 125and the second slit 126 are formed so that at least one of the firstslit 125 or the second slit 126 surrounds the display region 101.Therefore, the path for the electric charges 300 generated by the wiringcoupling of the gate line 14 to propagate to the display region 101 canbe taken long. Further, in the non-display region 102, the first slit125 and the second slit 126 are formed so that at least one of the firstslit 125 or the second slit 126 surrounds the display region 101, andhence propagation to the display region 101 of the electric chargesgenerated by the wiring coupling of various wirings other than the gateline 14 can be reduced. Note that, the second slit 126 may be formed ina region in which wiring other than the gate line 14 (for example,testing wiring) is arranged, in which the electric charges are generatedby the wiring coupling.

Further, it is preferred that each of the two end portions of the secondslit 126 be arranged in a region in which the first slit 125 is formed,and each of the two end portions of the second slit 126 overlap with thefirst slit 125 in a direction opposite to the direction in which the endportion of the second slit 126 reaches the display region 101 at theshortest distance. With this, the path for the electric charges 300generated by the wiring coupling of the gate line 14 to propagate to thedisplay region 101 can be taken long. Further, the end portion of thefirst slit 125 and the end portion of the second slit 126 may bearranged so that the distance therebetween is long. For example, each ofthe two end portions of the second slit 126 may be arranged in a regionin which the first slit 125 is formed, and each of the two end portionsof the second slit 126 may overlap with the center portion of the firstslit 125 in the direction opposite to the direction in which the endportion of the second slit 126 reaches the display region 101 at theshortest distance. With this, the movement distance of the electriccharges 300 moving from the first end portion E1 of the first slit 125to a first end portion E11 of the second slit 126 and the movementdistance of the electric charges 300 moving from the second end portionE2 of the first slit 125 to a second end portion E12 of the second slit126 can be set equal to each other.

Specifically, as illustrated in FIG. 10, the second slit 126 is formedso as to cover the end portion of the first slit 125 when thenon-display region 102 is viewed from the display region 101. Further, apart of the second slit 126 extends along the first slit 125 and betweenthe first slit 125 and the display region 101. Further, a part of thesecond slit 126 is formed through the third region 102C and the fourthregion 1025 in which the first slit 125 is not formed. Further, each ofthe first end portion E11 and the second end portion E12 of the secondslit 126 is included in the first region 102A. Further, the first endportion E11 is arranged so as to overlap with the first slit 125 in thedirection opposite to the direction in which the first end portion E11reaches the display region 101 at the shortest distance. Further, thesecond end portion E12 is arranged so as to overlap with the first slitin the direction opposite to the direction in which the second endportion E12 reaches the display region 101 at the shortest distance. Inthis case, the first end portion E11 and the second end portion E12 areformed so at to release the static electricity generated in the displayregion 101 to the outside of the display region 101, and the second slit126 does not surround the entire circumference of the display region 101in the present invention.

As described above, the shape and the arrangement position of the secondslit 126 are determined based on the shape and the arrangement positionof the first slit 125 (in particular, the position of the end portion ofthe first slit 125). When the second slit 126 is formed as describedabove, the electric charges moving on the outer side of the first slit125 can be prevented from moving toward the display region 101 at thefirst end portion E1 or the second end portion E2. Then, the electriccharges reaching first end portion E1 or the second end portion E2 movebetween the first slit 125 and the second slit 126, and then move towardthe display region 101 from the and portion of the second slit 126. Asdescribed above, the path for the electric charges 300 generated by thewiring coupling of the gate line 14 to propagate to the display region101 can be taken long, and hence the influence on the display image dueto the electric charges generated by the wiring coupling of the gateline 14 further reduced.

Note that, the second slit 126 is not limited to the shape illustratedin FIG. 10. The shape of the second slit 126 can be changed asappropriate as long as the path for the electric charges 300 generatedby the wiring coupling of the gate line 14 to propagate to the displayregion 101 can be taken long. For example, when the second slit 126 isfurther formed in addition to the first slit 125 illustrated in FIG. 5,the second slit 126 as illustrated in FIG. 11 may be formed. FIG. 11 isa view for illustrating a second example of the second slit 126 formedin the non-light transmitting layer 122 according to the secondembodiment. As illustrated in FIG. 11, the second slit 126 is formedbased on the shave and the arrangement position of the first slit 125.Specifically, the second slit 126 is formed so as to cover the endportions (first end portion E1 and second end portion E2) of the firstslit 125 when the non-display region 102 is viewed from the displayregion 101. Farther, a part of the second slit 126 is formed along thefirst slit 125 and between the first slit 125 and the display region101. Further, a part of the second slit 126 is formed through the thirdregion 102C in which the first 125 is not formed. Further, the first endportion E11 of the second slit 126 is included in the first region 102A.Further, the second end portion E12 of the second slit 126 is includedin the fourth region 102D. Further, the first end portion E11 isarranged so as to overlap with the first slit 125 in the directionopposite to the direction in which the first end portion E11 reaches thedisplay region 101 at the shortest distance. Further, the second endportion E12 is arranged so as to overlap with the first slit 125 in thedirection opposite to the direction in which the second end portion E12reaches the display region 101 at the shortest distance. Note that, inFIG. 11, the first end portion E11 and the second end portion E12 of thesecond slit 126 may be included in the second region 102B.

When the second slit 126 is further Formed in addition to the first slit125 illustrated in FIG. 7, the second slit 126 as illustrated in FIG. 12may be formed. FIG. 12 is a view for illustrating a third example of thesecond slit 126 formed in the non-light transmitting layer 122 accordingto the second embodiment. As illustrated in FIG, 12, the second slit 126is formed based on the shape and the arrangement position of the firstslit 125. Specifically, the second slit 126 is formed so as to cover theend portions (first end portion E1 and second end portion E2) of thefirst slit 125 when the non-display region 102 viewed from the displayregion 101. Further, a part of the second slit 126 is formed along thefirst slit 125 and between the first slit 125 and the display region101. Further, each of the first end portion E11 and the second endportion E12 of the second slit 126 is included in the first region 102A.Further, the first end portion E11 is arranged so as to overlap with thecenter portion of the first slit 125 in the direction opposite to thedirection in which the first end portion E11 reaches the display region101 at the shortest distance. Further, the second end portion 112 isarranged so as to overlap with the center portion of first slit 125 inthe direction opposite to the direction in which the second end portion112 reaches the display region 101 at the shortest distance. Note that,in FIG. 12, the first end portion E11 of the second slit 126 man beformed in the second region 102B, and the second end portion E12 of thesecond slit 126 may be formed in the third region 102C. Further, thefirst end portion E11 of the second slit 126 may be formed in the fourthregion 102D, and the second end portion E12 of the second slit 126 maybe formed in the third region 102C. Further, first end portion E11 ofthe second slit 125 may be formed in the fourth region 102D, and thesecond end portion 112 of the second slit 126 may be formed in the firstregion 102A.

Further, the second slit 126 may include a plurality of slits. Forexample, in FIG. 10 and FIG. 11, the second slit 125 may include twoslits, specifically, a slit formed so as to cover the first end portionE1 of the first slit 125 when the non-display region is viewed from thedisplay region 101, and a slit formed so to cover the second end portionE2 of the first slit 125 when the non-display region 102 is viewed fromthe display region 101. Further, FIG. 13 is a view for illustrating afourth example of the second slit 126 formed in the non-lighttransmitting layer 122 according to the second embodiment. Asillustrated in FIG. 13, for example, when the second slit 126 is furtherformed in addition to the plurality of first slits 125 illustrated inFIG. 8, the second slit 126 may include two second slits 126 (secondslit 126 a and second slit 126 b). The two second slits 126 may beformed based on the shapes and the arrangement positions of therespective two first slit 125 (first slit 125 a and first slit 125 b).Specifically, when the non-display region 102 is viewed from the displayregion 101, the second slit 126 (second slit 126 a and second slit 126b) is formed so as to cover end portion of the first slit 125 (firstslit 125 a and first slit 125 b). In FIG. 13, the second slit 126 a isformed so as to extend through the first region 102A, the second region102B, and the fourth region 102D, and the second slit 126 b is formed soas to extend through the first region 102A, the third region 102C, andthe fourth region 102D. Note that, in FIG. 13, the second slit 125 a maybe formed in the second region 102B, and the second slit 126 b may beformed in the third region 102C.

Based on the example of the second slit 126 formed in the non-lighttransmitting layer 122 according to the second embodiment describedabove, it can be said that at least one side of the non-display region102 (in other words, any one of the first region 102A to the fourthregion 102D) includes a region in which the first slit 125 and thesecond slit 126 extend in parallel with each other, and a region inwhich only the first slit 125 extends.

Further, as illustrated in FIG. 3 and FIG. 9, the non-light transmittinglayer 122 includes an overlapping region 103 overlapping with the upperframe 201 in plan view, and a non-overlapping region 104 free fromoverlapping with the upper frame 20 in plan view. The non-overlappingregion 104 can be easily viewed by a viewer, and hence it is preferredthat the first slit 125 and the second slit 126 described above beformed in the overlapping region 103. However, when there is no room forforming a slit in the overlapping region 103, the first slit 125 and thesecond slit 126 are formed in the non-overlapping region 104. Further, apart of the first slit 125 may be formed in the non-overlapping region104. When a part of the first slit 125 is formed in the non-overlappingregion 104, the end portion of the first slit 125 may be prevented frombeing arranged in the non-overlapping region 104.

FIG. 14 is a view for illustrating an example of the first slit 125formed in the non-overlapping region 104. In FIG. 14, the gate driver210 (gate driver 240 a or gate driver 240 b) is arranged in each of thefirst region 102A and the fourth region 102D. Further, the first slit125 includes two first slits 125 (first slit 125 c and first slit 125d). Further, the second slit 126 includes two second slits 126 (secondslit 126 c and second slit 126 d). The first slit 125 c is formed so asto extend through the first region 102A, the second region 102B, and thefourth region 102D. The first slit 125 d is formed so as to extendthrough the first region 102A, the third region 102C, and the fourthregion 102D. Further, a part of the first slit 125 c (part included inthe second region 102B) is formed in the non-overlapping region 104.Further, a part of the first slit 125 d (part included in the thirdregion 102C) is formed in the non-overlapping region 104. In this case,the two end portions of the first slit 125 c are respectively arrangedin the first region 102A and the fourth region 102D so as not to bearranged in the non-overlapping region 104. Further, the two endportioned of the first slit 125 d are respectively arranged in the firstregion 102A and the fourth region 102D so as not to be arranged in thenon-overlapping region 104. Further, the second slit 126 c is formed sothat, in the first region 102A, the second slit 126 c covers the endportion of the first slit 125 c and the end portion of the first slit125 d when the non-display region 102 is viewed from the display region101. Further, the second slit 126 d is formed so that, in the fourthregion 102D, the second slit 120 d covers the end portion of the firstslit 125 c and the end portion of the first slit 125 d when thenon-display region 102 is viewed from the display region 101. Asdescribed above, the end portion of the first slit 125 is prevented frombeing arranged in the non-overlapping region 104, and thus the endportion of the first slit 125 is hardly viewed by the viewer. Further,even when the end portion of the first slit 125 is arranged in theregion in which the gate driver 240 is arranged, the second slit 126 isformed so as to cover the end portion of the first slit 125 when thenon-display region 102 is viewed from the display region 101. Therefore,the path for the electric charges 300 generated by the wiring couplingof the gate line 14 to propagate to the display region 101 can be takenlong. Further, similarly, a part of the second slit 126 may be formed inthe non-overlapping region 104. When a part of the second slit 126 isformed in the non-overlapping region 104, the end portion of the secondslit 126 may be prevented from hexing formed in the non-overlappingregion 104.

Further, the width of the slit formed in the overlapping region 103 maybe larger than the width of the slit formed in the non-overlappingregion 104. With this, the passing through the slit formed in thenon-overlapping region 104 is hardly viewed by the viewer.

Further, the second slit 126 may be formed on the outer side withrespect to the first slit 125. FIG. 15 is a view for illustrating anexample of the second slit 125 formed on the outer side with respect tothe first slit 125. In FIG. 15, the gate driver 240 gate driver 240 gatedriver 240 b) is arranged in of the first region 102A and the fourthregion 102D. Further, the first slit 125 is formed so as to extendthrough the first region 102A, the second region 102B, the third region102C, and the fourth region 102D. Each of the two end portions of thefirst slit 125 is arranged in the third region 102C. A part of the firstslit 125 (part included in the first region 102A, the third region 103C,and the fourth region 104D) is formed in the non-overlapping region 104.In this case, when wiring such as the testing wiring, in which theelectric charges are generated by the wiring coupling, is arranged inthe third region 102D, the second slit 126 is formed on the outer sidewith respect to the first slit 125 in the third region 102C. With this,the path for the electric charges generated by the wiring coupling ofthe testing wiring or the like to propagate to the display region 101can be taken long, and hence the influence display image due to theelectric charges can be reduced.

Further, each of the first slit 125 and the second slit 126 may befilled with a color resist of blue, red, green, or the like. Forexample, when each of the first slit 125 and the second slit 126 isfilled with the blue resist, the color of the light passing through eachof the first slit 125 and the second slit 126 is blue. Thus, when theviewer close to the display surface views the non-display region, thelight passing through each of the first slit 125 and the second slit 126is obscure.

Further, in the above mentioned embodiment, there is described anexample in which the first slit 125 and the second slit 126 are formedthe non-light transmitting layer 122, but three or more slits may beformed in the non-light transmitting layer 122.
